LinuxでGPUと共有されるいくつかのシステムメモリを追加するには？

Question

NVIDIAバイナリドライバでは、GPUが使用できるシステムRAMの量を指定できません。私もnouveauこれが許されるという言葉を聞いたことがない。

NVIDIAドライバの最新の安定版のオプションは次のとおりです。

NVreg_MemoryPoolSizeは興味深いようですが、必要ではありません。

 * Option: MemoryPoolSize
 *
 * Description:
 *
 * When set to a non-zero value, this option specifies the size of the
 * memory pool, given as a multiple of 1 GB, created on VMware ESXi to
 * satisfy any system memory allocations requested by the NVIDIA kernel
 * module.

ただ楽しんで次のようにしてみましょう。

/etc/modprobe.d/nvidia.conf
options nvidia NVreg_MemoryPoolSize=4

私はこれがうまくいかないと確信していますが。 Windows働く違う、それはすべて問題です。
